To all (room it may concern:

Be it known that I, GEORGE W. BEADLE, a citizen of the United States, residing at Bayonne, in the county of Hudson and State of New Jersey have invented certain new and useful Improvements in Machines for Closing Paper Cartons; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to machines for making paper cartons, and especially to that portion of the mechanism of such machines which inserts the closure in the carton body during theprocess" of manufacture, and has for its object to produce a mechanism which will insert disk closures in already formed tubes in a manner more eificient than the mechanisms which have been heretofore proposed.

lVith this and other objects in view, the invention consists in the novel details of construction and combinations of parts more fully hereinafter disclosed and particularly pointed out in the claims.

This inventionis an improvement on the invention describedand claimed inmy copending application #673,084 filed January 24:, 1912, and entitled Machine for making paper cartons.

Referring to the accompanyingdrawings forming a part of this-specification, in which like numerals designate like parts in all the views z -Figure l an end elevational view of the general mechanism employed in producing carton bodies from a continuous strip of paper; Fig. 2 is a sectional view illustrating the closure forming and inserting mechanism in its retracted position; Fig. 3 is a like view of said mechanism when it has advanced almost-to the point of cutting a pa per disk from the paper strip out of which it is formed; Fig. l is a view similar to Fig. 2, but showing the parts in their final position after the disk has been formed and insorted in the bottle mouth; Fig. 5 is a sectional plan view taken on the line of Fig. a looking in the direction of the arrows; Fig. 6 is a sectional view taken on the line 6-6 of Fi 4: looking in the direction of the arrows; Fig. 7 is a sectional view taken on the line 7-7 of F ig. 6, looking in the lirection of the arrow and illustrating only the clrcular portion of the ring which moves down over the bottle mouth when the closure is being inserted; Fig. 8 is a view of the ring removed from the machine, as seen in a direction opposite from that of the arrows 1n Fig. 4, and showing the guide rods and guide pieces for the ring in section; Fig. 9 1s a diagrammatic view illustrating the various positions of the mandrels during the process of finishing the carton bodies and also showing in end elevation the mechamsm for forming grooves in the bottle bodies; Fig. 10 is a side elevational view of the mechanism shown in Fig. 9, for forming grooves in the bottle bodies; Figs. 11, 12 and 13 are sectional views illustrating varlous steps in the completion of the bottle closure; Fig. 14 is a diagrammatic view of the plunger and bottle mouth showing on an exaggerated scale that the bottle closure is larger than the bottle mouth; Fig. 15 is a plan view of the mandrels for forming the tubes, and of the crimpin mechanism coacting with said mandrels or closing the said tubes; and, Fig. 16 is a sectional view of the mechanism shown in Fig. 15.

Referring first to Fig. 1 and to my copending application above, it will be understood that the paper strip 2 is unwound from the roller 1, passes through a guide tube 3, is severed by a knife 4 into suitable lengths, paste is suitably applied thereto as at 5, and the severed and paste coated strip is wound upon the mandrel 6, mounted on the revolving carrier 7 secured on the shaft 11. The carrier 7 has associated. therewith the gear 8 which meshes with the gear 9, mounted on the shaft 10.

The means for forming the tube illustrated in Fig. 1 form no part of my present invention, and are here only illustrated in order to render clear the operation of the closing mechanism to be described below. However, it should be said that the mechanism illustrated in Fig. 1 is so timed that the various mandrels 6 first receive the paper as there illustrated, wind the same into suitable tubes, and thereupon, as the frame 7 revolves, each mandrel brings its tube to a position where the latter is dried, and then opposite a closing mechanism for inserting disk "closures into the already formed and dried tubes, then in register with a crimping mechanism whereupon the outer edge of the tube is'crimped over the disk which has been inserted in said tube, the-n opposite a grooving mechanism, whereupon an inwardly :extending groove is formed in the body of the tube just below the inserted disk to support the same, and finally the said mandrels bring the tubes toa position where they are discharged from the machine, all as is dia- 7 i vessels that are destined to hold liquids, it is essential that an exceedingly tight closure be formed, because otherwise. owing to the nature of the material and the subsequent compression of the liquid ,fillcdpackage durmg handling, the contentsare liable to leak and thereby destroydthe eflicieney of the package. v

In order to provide an exceedinglymexpensive and at the same time, a very efficient closure, I have devised thefollowing mecha nisni for inserting closures in the mouths of paperbottles which are slightly larger than the interior of said mouths. Th'at is to say,

. by mymachine, disks of papenma'y be cut 'out, of a. diameter say one-thirty-second'of an inch larger than the interior diameter of the bottle mouth, and forced into the bottle mouth without raising a bur, and forming exceedingly tight and efiicient closures which i gives perfect satisfaction in practice.

Referring more particularly to Figs; 2 and 3, the paper 13 out of which the closures are formed, is suitably fed from the roll 1 along the channel-wayv l5 and in the path of t he cutting die 16, reeiprocated from the shaft 12 by means of the connection 17, all as is fully disclosed in my copending application above. In said applicatiomhowever, theinsorting plungerloeated on the interior of the cutting die 16 is non-expanding and therefore, of necessity must be of a' diameter smaller than the diame r the cut disk by at least twice the thickness of the walls of the ,cutting die 16. Sucha on-expanding plunger, therefore, would be of a less diameter than the interior of'the bottle mouth, and if it is attempted to force a disk into the bottle. mouth which is larger than the a e-by su h a nxpa d nsp eb would inevitably form around the edge of said disk on the interior o f'the bottle mouth,

and a bad joint would result. Therefore, my present invention difl'ers, among other'featuresfrom the former'invention, in that the inserting plunger 18 of the present invention snf swarmin use nd" er is extreme outer edge leaves the cutting plunger '16, it expands outwardly to the diameter of the interior of the bottle mouth, and thereupon fits the said interior v so/that novburis formed on the said disk during the inserting operation, as will appear below. r

The paper- 13 being fed by the mechanism disclosed in my application above, underneath the cutting plunger 16, the latter moves toward the right, as shown in Figs. 2 and 3,

and cuts a disk from said paper which is slightly larger than the interior of the bottle mouth 20. -As the shaft 12 continues tore-*- volve, theinserting plunger 18 moves lf o l';

ward. This said plunger may be of any suitableexpanding type. but preferably is coinposedpf the spring fingers 21 which are normally, somewhat compressed when they are on the inside of the plunger 16, as illustrated in Figs. 2 and 3. but will expand to the full diameter of the interior of the n1outh 20,as.

illustrated in Fig. 4, as soon as they lease yond the convex surface of the plunger memf ber 23, and therefore as the fingers 21 and member 23 advance, the said pin 24: first contacts with the disk 22 and tilts the same. as. diagrammatically illustrated in Figs. 11 and 14. In this tilted position, .oneend of the diameter of the disk rests inside the bot tle' mouth near the end of the mandrel 6, while the other end of the said diameter is about entering the bottle' mouth so that al though the disk is slightlv lar er than the bottle mouth, yet at the same tiiiie,-it canbe accommodated within the same in item clined position. i

It is now evident that if a plunger, suchas interior of the bottle mouth, should force the disk home, a bur would be raised along the outer edge of the disk and on the interior of the bottle mouth. thereby causing a'bad 2,3, which is smaller than the diameter of the iJuring this further advance of the closing plunger, the pin 24 moves toward the left, as seen in Fig. 4, and against the action'of its spring 25, as will be readily understood" 1 The extreme end of, the mandrel 6 being #QflcaveQandthat of the plunger'member 2Z5 beingfconvex, as shownmthe diskj2 2fis ees? sl ll uri -e mi s paper stock, it is evident that the'outw'ard pressure of the disk 22 isliableto unduly stretch the same, ,and thereupon prevent the joint from being'as tight as'may be desired. Accordingly, in order to support the exterior of the mouth 20, I hayejprovided the ring 30, having the, guide pieces 31 fitting the interior of the orifice in the plate 32, through which the disk 22 is forcedyand adapted to sl-idefoutWardly over the bottle mouth from its position shown in Figs. 2 and 3, to its position shown in Fig. 4,,aswill 110W. bedfplate 32"and passing through the same, are the guide pins 85 controlled bythe springs 36 and provided at one endwith' the bearingpieces 37-against which a flange of the cutter 16 is adapted to contact during its cutting operation. The other end of the p1 s35, lit the ears 39 of the ringmember 3,0, and when this said contactftakes place, the said ring-member is forced from its normal position, shown Fig. 3, for example, to its position'over the bottle mouth'shown in Eig. 4, and thereupon effectually supports the exterior of the b'ottle'mouth and prevents it' from being unduly pressed '1 outward during the disk 'closing operation. After the bottle mouthfQO has thus received its disk, the membe'rS'IG and 18 recede into the position shown in Fig. 2, and the said springs 36 return the ring member 30 to its normal position. The bottle body'27 having now been provided'with an end closure, the shaft 11 is automatically rotated 60 and the mandrel 6 carrying the closed tube '27 is brought to the crimpin position indi- Gated i l s- The S Q'W l'hitLfifl fully disclosed in 'my said tipplication 'aboiie,

is of the expanding type, and'preferably of the construction shown igsf15 and 16. The mechanism by which the said mandrels are expanded, forrnno part of: the present invent'fon, andtherefore, Wlllj lllOlS be de scribed hereinfurther than to say that through suitable mechanism, the shaft 40 is reciprocated, which, through the wedge members e1, forces outwardly the segments 42, and thereupon holdfirmly the carton body .Q'Kiiagains't turning. When the said mandrels 6 reach the crimping positiomthey are in register with the crimped tool 43, which is rapidly turned by means of the gear 44 on the shaft 45, as disclosed below and. the extremeedge or mouth 20ofthe tube 27 is turnedbver or 'crimped in, as

sion

illustrated, in Figs. 12', 13 "and-16f. The

crnnped oyer edge is chosen of dimenie sw etera sessat be described? Mounteduponthe said but order to iurther strengthen the joint thus forined, and also to insure that the disk122 jsh'allbe firmly locked. in place, the mandrel'ti 'is next moved another 60and carriestheclosed tube 27 from the crimping position to the grooving position, as indicatedin Fig.9. The mandrels 6 are further providedw th the gear 4 6, which causes the same to'rotate upon their axes by the means about to be described. v v

At the grooving positionf,,l have provided a grooving tool 47, the edge of which is eccentric to the path of, the outer edge of the moving body 27, and intersects the said path ,toa sight degree, or to an amount equallto the-depth of the groove it is desired to form in the'said body27, Accordingly, asthe mandrel 6 reaches thesaid grooving position, a gear 48 (Fig. 10), meshes with the gear ifion the mandrel, and rapidly rotates the same. That is to say, said gear 48 is mounted upon the shaft 49 carrying the sprocket 50 over which passes the sprocket chain'51, and which chain is driven by the motor 52 provided with a. gear 53, which also'meshes with the gear 4% driving the shaft dli'and crimping" tool 43. Thebody 27 of the tube bein thus ra' idly rotating while firmly held by t e expanding mandrel 6,and the edge of the tool 47 thusintersectiiig'the path of the said tube 27, a groove 55 of pre, determined depth is formed in the body portionioi? the tube, as will be clear from Figs. 9, 12 and 13. In order to facilitate the formation of'this groove, the mandrel 6 1s provided'with a groove 56 (Figs. 10 and 1%) into which the material of thetube may be forced, 1 Since-it is often necessary to close-tubes 27 ofidifi'er ent lengths, I have provided 'a p'lurality of grooving tools i'i and have also provided a plurality of gr0oves, such as 57, 58 and', 59 in the mandrel. 6 to accommodate theftubes of different lengths. The' said tools Hare adjustable in and out along the slideways 60, and the screws '61 facilitate a still finer adjustment.

The position of the grooves 56, etc, in

the mandrels 6, are so chosen that the groove 55 formed'in the tube will be immediately under the disk 22, and will tend to force and tende s at rte sistanefe, owing to the pre'ssiireEof'saidai-r, is inet witli during the, disk closing opf'eration. f I The mechanism is perfectly automatic as will be understood from my copending application above, and after the tubes receive their grooves 55, they are discharged from the machine, when the mandrel is ready for 10 the reception of an additional strip of paper preparatory to the formation of new tube.
